The invention relates to shipbuilding, namely, devices for active control is as such active rudders, thrusters, retractable propulsion and steering swivel column (VDRC), thruster wing propulsion (see the book Kulagina C. D. Theory and the device of offshore fishing vessels. L., Shipbuilding, 1974, S. 332-336). Their widespread adoption due to economic feasibility, because the operation of the mooring and maneuvering can be performed without the use of port tugs. SAU create the possibility of control of the boat in the cramped conditions of the port water area, reduce the time and improve the safety of the maneuver.

A disadvantage of the known devices is the inability to accommodate them unsuitable for this vessel, as required for the installation of the ACS revision of the housing. Installation of additional devices on the underwater part of the hull leads to an increase in its resistance, and therefore, additional fuel consumption and reduce speed.

Retractable propulsion and steering columns are supplied with propeller screw or set screw-cap, which creates a stop, the direction of which can be changed in the horizontal plane within 360 degrees (similar - see the book above). It is possible to install two aft WDRC or in any part of the body.

Also known wing propulsion (Kirsten - Boeing and Voith - Schneider), creating emphasis in any direction in the horizontal plane and allowing to eliminate the need to have on Board the wheel and reverse main engine. The engines provide high maneuverability of the vessel and applied at port vessels and tugs (see T. C. Gilmer. The design of a modern ship. L. , Shipbuilding, 1974, S. 172-173). These engines combine the functions of motion control and maneuvering, but is ineffective for high-speed vessels (Kanaev, A. A. Energy vessels in the future. L., Shipbuilding, 1967, S. 86-87).

The known device off and then on.with. USSR N 1104056 propulsion and steering complex containing two propulsion and steering columns located at the extremities of the body floating in its center plane, can only have very limited use as a means of providing maneuvering the value of the specified penetration propellers columns) significantly enhances the overall length of the vessel due to submerged and non-observable parts of the rods speakers what makes maneuvering in narrow waters and creates additional prerequisites damage to the navigation of the vessel. On the use of the device.with. USSR N 1104056 for positioning the vessel (hold it over the point of drilling) and place it in the "off" position to move have the appropriate link in the description for the specified as. C.

The claimed invention is directed to solution of the problem consisting in the creation of highly efficient propulsion and control system for traffic control and maneuvering of vessels, the installation of which does not require modification of the underwater part of the hull. Achievable technical result is expressed in the creation is sufficient to move the ship efforts on the wing of the devices in the non swirling fluid flow created by the injection part of the unit with the drive of a small power.

The inventive device includes two propulsion and steering columns, including screws and attachments. When this column is posted on the hull of the vessel at a distance from each other, spaced along the length or width of the vessel. Each column is equipped with coaxial screws opposite rotation, optimized for creating non swirling flow. Nozzles n which is from each other.

The nozzles are pivoted in a horizontal plane within 360 degrees and is fitted with a toothed wheel cooperating with a rack on the piston rod of the hydraulic cylinder column. The column is equipped with a frame sensors and a control system which provides for the movement of the vessel in any direction at a consistent rotation nasdaw both columns at specified angles and fixing them in these terms.

The device is made removable.

The device combines the functions of movement, control and maneuvering, provides a highly efficient and economical movement, management, and maneuvering at all speeds (from the full stroke and small, in the open sea or cramped conditions of the water area of the port) and can also be used as a highly efficient main engine.

The proposed device can be used as the main propulsion underwater vehicle that provides the maneuvering in any direction in space (in the horizontal and vertical planes), and when placed in the median plane of the apparatus and equipment of the drive steerable propellers reversing engines and also modes of immersion, emersion and running trim "mlaysia more rational use of energy to generate the driving control force. In the inventive device, this force is transverse (lift) force wing, placed in the square of the fluid flow created coaxial screws opposite rotation, optimized for creating non swirling flow, and the wings set at an angle to the direction of flow and at a certain distance between them. The magnitude of the lateral force wing exceed the power of his drag, and commensurate with her original force - stop screws.

If equal quantities are developing efforts (stops) the power consumed by the claimed device is 2 - 10% of rated power of the main engine for the corresponding screw propulsion (depending on the speed of the vessel), i.e., the inventive device is able to provide the movement of the vessel in the entire range of speeds from the drive of low power with a corresponding reduction in fuel consumption.

The technical effect of the use of the claimed device is provided by the spacing of the two propulsion and steering columns, creating a driving-control forces.

You have the following options for speaker placement:1 - unilateral placement of the speakers placing the speakers, smashed Tricine paportnoe placing the speakers (spaced across the width of the body) - placing the speakers one on each Board, in the middle or aft of the vessel, corresponding to the mode of surdulescu", including the related symmetric paportnoe placing the speakers in the aft end of the vessel;3 - asymmetric paportnoe (diagonal) placement of speakers placing the speakers one on each Board, one aft, and the other in the middle part of the vessel, corresponding to the "intermediate" mode.

For double-hulled vessels possible speaker placement in the diametrical plane of the vessel, spaced along its length.

The inventive device is explained using the drawings:Fig. 1 - General view of the proposed device in embodiment 1 of the placement of the propulsion and steering columns, provides a mode of "super",Fig. 2 - General view of the propulsion and steering column, front view,Fig. 3 - the same, lateral view,Fig. 4 is a diagram of the forces generated by the device in embodiment 1 of speaker placement, it provides a mode of "super" at different positions of the rotary nasdaw columns.

The proposed device consists of two identical propulsion and steering columns 1 and corresponding control system (Fig. not shown is 5 mounted in split bearings 7 on the frame 2 and provided with a toothed wheel 8, located in engagement with the toothed wheel 9 of the transmission 4. The inner shaft 6 is mounted in bearings 10 on the inside of the hollow shaft 5 and the clutch 11 is connected with the second output shaft of the transmission 4. The free ends of the shafts 5 and 6 supplied screws 12 and 13 in opposite direction of rotation. In the area of the screws 12 and 13 of the frame 2 provided with a cowling 14. Rotary nozzles 15 is mounted in a bearing support 16 of the frame 2 and provided with a toothed wheel 17, interacting with the rail 18 of the hydraulic cylinder 19. Nozzles are made with wings 20, is inclined relative to the axis of the screw and located at a certain distance from each other. The angle of inclination of the wings to be confirmed experimentally. On the frame 2 installed sensors of the control system (Fig. not shown), the locking position of the rotary nozzle 15 with respect to the frame 2.

The mounts propulsion and steering columns 1 in the working position two special beam 21 are placed on both sides of the ship, in pairs, in its middle and aft. In the travelling position of the column 1 is placed and fixed on the deck of the ship.

The device works as follows (option 1 describes the placement of the propulsion and steering columns 1, provides a mode of "super", see Fig. 1). Grupowy what her part, another in the stern of the vessel into two beams 21.

When enabled, the actuator 3 coaxial screws 12 and 13 create non swirling flow of water in the area of the wings swivel nozzle 15, which creates a force transverse direction (with respect to stream within the column 1). Depending on the location of the wings nozzle 15 with respect to the median plane of the ship changes direction driving control (transverse) force.

Turn the nozzle 15 at a desired position by a hydraulic cylinder 19, the piston rod which is fixed to the rail 18 which engages with the toothed wheel 17 of the nozzle 15. The position of the nozzle 15 is fixed sensors of the control system providing a consistent rotation nasdaw both columns at specified angles and fixing them in position.

The scheme of the forces generated by the device shown in Fig. 4, corresponds to the following maneuvers of the ship:NN 1, 2 - movement lagNN 3, 4 - a back and forth motionNN 5, 6 - turn on the spotNN 7, 14 - circulation to the front and rear flyN 15 - a motion by the Board in a random direction (marked on the diagram - DK1 and DC - propulsion and steering columns, respectively).

All options for speaker placement, the device is Ozolina direction, turning on the spot and circulation, i.e., maneuvering options for the layout of the device, a rotary nozzle columns that differ only quantitatively, depending on the distance between the nozzles and their arrangement relative to the center of mass of the ship.

Regulation of the magnitude of the driving control force is produced due to a change in flow velocity (rotational speed of the screws of the device) - coarse control, changing the installation angle of the wing - precise control and direction of its action in the horizontal plane due to the rotation of the nozzle.

Some reduction in maneuverability on the 2nd option layout is compensated by increasing the speed up to 20-30 knots, stability on the course and distance. Options 1 and 3, in addition to "super", also increase the average speed of the vessel in waves because of the low probability of both propulsion and steering columns simultaneously in the troughs of the waves.

Additional, almost 50 percent increase in total driving force of the columns is provided at the adjacent symmetric robertom placement of speakers in aft end of the ship and backlash-free placement of the cheeks adjacent nasdaw (or overlapping cheeks according to the health components of their wings nasdaw), while maintaining the same total area of the wings, and change the wrap mode, single wing, compared to the original (if separate accommodation), provides the increase of the driving force.

The flexibility of the inventive device is provided by the presence on both sides of the ship mount propulsion and steering columns and execution of propulsion and steering columns removable, i.e., creates the possibility of applying the optimal layout of the device to perform specific tasks.

High effectiveness of the proposed device can be used as a highly efficient main propulsion of the vessel, additional advantages which are: to improve the survivability of the vessel due to the exclusion of the cutouts in the housing, for outdoor installations, columns and large raznesennost, security screws columns from the navigation damages, as well as complicating the detection and identification of the vessel as a goal due to a change in orientation of the maxima of physical fields of a lesser intensity generated by the device.
